Question 1

What is the difference between Microsoft Teams Direct Routing and Operator Connect?

Accepted Answer

Microsoft Teams Direct Routing connects your Teams environment to the Public Switched Telephone Network (PSTN) via a Session Border Controller (SBC) and a PSTN carrier of your choice — giving you full control over your telephony carrier, routing rules, and SBC configuration. Operator Connect is a managed Microsoft program where certified operators (like CallTower) deliver PSTN connectivity directly through the Teams Admin Center, eliminating the need to manage SBC infrastructure yourself. Direct Routing is more flexible and suitable for complex or highly customized environments, while Operator Connect offers a simpler, operator-managed experience with faster deployment. CallTower offers both models, including specialized Direct Routing for GCC High (government/defense) environments, and Fibi can help you evaluate which approach best fits your infrastructure, compliance requirements, and IT team's capacity.

Question 2

What is GCC High and which businesses require it?

Accepted Answer

GCC High (Government Community Cloud High) is a Microsoft cloud environment specifically designed to meet the security and compliance requirements of US federal government agencies, defense contractors, and organizations subject to ITAR (International Traffic in Arms Regulations), DFARS (Defense Federal Acquisition Regulation Supplement), or CMMC (Cybersecurity Maturity Model Certification). It is a separate, isolated cloud from the commercial Microsoft 365 environment, with data centers and operations limited to US soil and US persons. Organizations in the Defense Industrial Base (DIB), contractors handling Controlled Unclassified Information (CUI), and companies with DoD contracts typically require GCC High compliance. CallTower's Teams Direct Routing for GCC High enables these organizations to add PSTN calling capabilities to their GCC High Teams environment — a technically complex integration that few carriers support.

Question 3

What is CallTower Connect and what does it enable?

Accepted Answer

CallTower Connect is CallTower's proprietary provisioning and management portal that gives customers and partners direct access to manage their CallTower services — including user provisioning, phone number management, call routing configuration, and service changes — without requiring a ticket or support call for routine tasks. The platform exposes 25+ APIs, enabling integration with CRM systems, ITSM platforms, and other enterprise tools for automated provisioning workflows and programmatic management at scale. For larger organizations or MSPs managing multiple client environments, CallTower Connect significantly reduces the operational overhead of day-to-day communications administration. It is one of the key differentiators that makes CallTower particularly strong for complex or multi-location deployments that require programmatic control.

Question 4

What CCaaS platforms does CallTower support, and can they integrate with Teams?

Accepted Answer

CallTower's cloud contact center portfolio includes Five9, Genesys, its own CT Contact Center platform, and Webex CCaaS — giving organizations flexibility to choose the CCaaS platform that best fits their agent workflows, reporting requirements, and existing technology stack. All of these CCaaS options are designed to integrate with Microsoft Teams, enabling agents to operate within a unified communications environment rather than managing separate platforms for internal collaboration and customer-facing contact center operations. CallTower's managed and professional services team supports CCaaS implementation, migration, and ongoing management — reducing the complexity of deploying and integrating CCaaS alongside Teams. Fibi evaluates all CCaaS options side by side and can help identify which platform best fits your contact center requirements and budget.

Question 5

What does white-glove implementation mean in practice?

Accepted Answer

White-glove implementation at CallTower means the transition to new communications infrastructure is managed in a gradual, guided process rather than a full cutover — prioritizing user adoption and minimizing disruption to day-to-day operations. CallTower's implementation team handles technical configuration, user migration sequencing, training coordination, and post-deployment validation rather than handing off a provisioned environment and expecting the customer's IT team to manage the rest. For organizations migrating from legacy PBX systems or complex on-premise telephony environments, the gradual shift model allows departments or user groups to be migrated incrementally with validation at each stage. This is particularly relevant for international environments, hybrid UCaaS deployments, or organizations integrating CCaaS alongside Teams — where coordination complexity is high.

Question 6

Does going through Fibi change my CallTower contract or pricing?

Accepted Answer

No. Your contract is signed directly with CallTower — Fibi is not a party to it and does not add a layer to the pricing. CallTower operates through a channel model that includes technology advisors like Fibi as part of their go-to-market, and Fibi's advisory is funded by a commission CallTower pays from their existing channel budget — it does not affect your invoice in any way. Fibi evaluates CallTower alongside other UCaaS, Teams, and CCaaS providers to ensure you are getting the right platform fit and competitive pricing for your environment. The value Fibi adds is independent advisory, side-by-side comparison, faster quote turnaround, and ongoing support — at zero cost to you.
